Application.;:filed VJIayJ., 19,23.' Seria-L 110563558139. Y

To all whom imag concern Jr., a citizen lof, the United States ofAmerica5-. residing: a-t Birmingham, inthe county of Jeiferson=aiid.Statefof Alabama,

have invented certain new andvuseful Img.L provenients in VV-heelPullers, of which the following `ris. a specification.; I

Myiin'vention relates topa .dev-ice for pulfl.

ing wheels from shafts or aXlesu-pon .Whili they are mounted.

My invention is more particularly adapted fo1;-.the`.pull ing lofautomobile wheels from the. taper axle upon which theyV 4.are pressed,-though obviousl by lincreasing the-i size and strength of the;apparatus, it maybe adapted toL-.pullfrailroad car. wheels. from`V.their axles.

My u. invention' .contemplates the combinaa tion of a socketmemberthreadectto. engagek thehub of vther-wheel; .toebefdira-wn.landadapted to. i detachabl'yf interlock i with f a chuck-whichyislformed with, a tool grip and provided. with a screw adapted-V.. to,pass. loosely.through the socket. The socket. .is-` preferablyreversible.infthe` chuck-.and prak vided; at ite ends;withthreadedfreceesee Or wheel engaging k elements offdifferent diameterto adapt each of my improvedff sockets for use with wheelshavingfgdi-fferent hub dimensions.

My invention also contemplates utilizing the chuck screw as a means forholding the socket in interlocked relation with the chuck so that, bymeans of a wrench applied to the chuck, the socket can be screwed homeon the wheel hub or unscrewed therefrom.

My invention contemplates the provision of the socket with anintermediate recessed seat presenting on opposite sides straightparallel walls which are adapted to interlock snugly. withcorrespondingly shaped shoulders at the outer end of a socket receivingrecess in the chuck.

My invention also comprises the novel details of construction andarrangements of parts, which in their preferred embodiment only areillustrated in the accompanying drawings which form a part of thisspecilication, and in which:-

Fig. 1 shows the complete wheel puller in upright position.

A. groove 11i iscut' about themiddle ofthe.

socket 8,l said-gropve being of uni-.form depth. around one half ofitsf,.circumferenceand tapering `at La tangent-from oppositefsides,asisbetterillustratedan The chuck portion of the wheel puller is formedwith the recess 12 which is circular in shape about one ha-lf of itsinside circumference and provided with a straight side opening to permitthe entrance ofthe hub engaging socket. The chuck shoulder 18 co-actswith the socket groove 11 and serves to hold the socket interlocked withthe chuck against relative longitudinal or rotating movement thoughpermitting a lateral movement of the socket to disengage it from thechuck.

Between the recesses 9 and 10 in each socket 8 is left a web 14 having acentral aperture 15, unthreaded and aligning with the screw hole 4 whenthe socket is mounted in the chuck. The screw 5 will pass freely throughthis web aperture 15 and hence will hold the socket interlocked with thechuck. By backing the screw out of the chuck recess 12 the desiredsocket 8 can be inserted in the chuck or the one in place reversed.

I show my invention adapted to pull an automobile wheel 16 by its hubflange 17 from the axle 18. The hub fiange has a threaded end 19 adaptedto receive the hub cap and also adapted to screw into the socket recess10, when the screw 5 will be in position to engage the yaxle 18 as it isscrewed in through the chuck body and will act to pull the wheel oii theaxle. The socket can be screwed onv the hub flange by applying a wrenchto the hex portion l of the chuck body and turning it with the socket 8interlocked therewith for rotation, due to the tact that the straightsides of its groove ll will not permit it to rotate in but only with thechuck.

rIhough I have described with great particularity the details of theembodiment of the invention herein shown, it is not to be construed thatI am limited theretofas changes yin arrangement and substitution ofequivalents may be made by those skilled in the art `without departingfrom the invention as dened in the appended claims.

Having thus described my invention, what I claim as new and desire tosecure by Letters Patent, is

1; A wheel puller comprising a chuck having a laterally opening recess,a screw working longitudinally through said chuck and recess, a socketmember removably mounted in said recess, means to interlock said socketywith the chuck against relative longitudinal movement, and means on thesocket to engage a wheel hub, 'there being a central aperture in thesocket for the passage of said screw.

2. A wheel puller lin accordance with claim l, in which said socket isreversible and has means at its ends to engage different sized wheelhubs.

3. A wheelf puller vin accordance with claim 1, in which the chuck isprovided with a tool grip and interlocks with the socket to cause thelatter to rotate with the chuck, said socket having screw means toengage the wheel hub.

4. In a wheel puller, in combination, a chuck having an axial threadedbore, a tool grip atA one end and a recess at the other end with socketengaging shoulders, a socket adapted to be moved into said recess andinto interlocked engagement with said chuck shoulder, said chuck andsocket having their engaging portions adapted to un lock them 'forjointrotation, said socket having threaded seats of different diametersat its opposite ends, a center aperture aligning with the threadedopening in the chuck, and a screw engaged in the chuck opening andadapted to pass freely through said aperture in the socket in positionto engage a wheel axle when the socket is in threaded engagement withthe hub on said axle.

l5. A wheel puller comprising a body having a plunger mounted thereinand associated with means adapted to force the plunger axially throughsaid body, and a socket member detachable from the body and internallythreaded to screw on the hub to be pulled, said member and body having Ainterlocking parts to prevent relative movement axially oit' the plungerwhile pulling a wheel, and said socket having dierent sized threads atopposite ends and being adapted to be interlocked with said body witheither end exposed. y

In testimony whereof I alix my signature.
